<p>The trigger system rotary speed sensor, preferably operates without mechanical contact. It produces a signal which is evaluated in coupled electronics. The system also includes an electronically-controlled auxiliary coupling (H). When triggered, this brings a brake jaw into contact with a rotor (7) of the speed limiter. This causes the brake jaw unit (12) to pivot and rest against the rotor (7) such that self-intensification of the braking force results. As a result, the rope pulley (4a, 4b) is braked.</p> |
